            at runtime in order to enable CoAP debug output via the ESP
            log mechanism.

            Note: The Mbed TLS library logging is controlled by the mbedTLS

            this needs to be enabled to support the ongoing session going to
            the next hop.

            If this option is disabled, redundent CoAP client only code is removed.
